| Summary: | The concept of zero linear ablation is introduced to describe the mass
ablation without shape change, and it is employed to design thermal
protection materials under an extreme thermal environment. Aluminizing carbon
composites are used as a sample to study numerically the heat response. As
indicated in the numerical results, the shape of the composites did not
change under a high heat flux because the phase transition (melt or
evaporation) of aluminum can absorb a lot of energy before the ablation of
carbon, and the zero linear ablation depends on not only the volume fraction
of aluminum, but also the heating period and the heat flux. |
